SDI/COMPOSITE VIDEO SWITCH CARD INTERCONNECTIONS
Each Video Switch Card can cross-switch two video output sources between two receiving devices. Output
from one video source is connected to Switch Card input "A." The input to the receiving device is con-
nected to Switch Card output "A.” Output from a second video source is connected to Switch Card input
"B." The input to a second receiving device is connected to Switch Card output "B." When the switch is
thrown, source "A" is connected to receiving device "B" while source "B" is connected to receiving device
"A." This card can be used to switch composite analog or SDI video signals. Cable connections are made
using SDI compatible cabling terminated with 75 Ohm BNC connectors.
There are two SDI Switch Cards in the Master Module. One card connects to Program output on PVTV
NEWS, and the other connects to Preview Out on PVTV NEWS. Refer to Tables 2 and 3 for more informa-
tion.
